Say you bring up a web page and it is called Page A. Page A is a web page that has a Text field with a submit button. When you type in some text into the text field and hit submit, you post the content in the text field to PAGE B and you (the user) goes to a PAGE C. Page A will then be included into Page D. When you visit Page A a second time the TextArea is populated with the content you submitted the last time. When the text field is changed again it removes the old content and saves the new content.

My question is how do i make the Text box on Page A be populated with the content on PAGE B.

CMS is what im trying to design, i want somone to be able to goto an edit page and edit text content in a simple text box...... and send/save button..... when they go back to the edit page the contect that they posted the time before is in the text box, if they wish they can change it and send/save.

you should first send the thread ID to the edit page using Session variable. Then in the edit page, using MySQL and the thread ID, retrieve the data about that particular content and put it as the value of the text area.
Now if Send/Save button is pressed, save the data in database using thread ID and value as the new value of the text area, else don't save the data in the database.

I hope i have understand your question in this manner, hope this will help you.... If it helped you add it to my reputation. Thanks

Your on the ball Josh Connerty. I would like to stay away from the data base do to maintenance. I will make it in a database if i have to.
thanks

So you wish to edit the file that contains the content for the specific page?

In this case you may want to take a look at w3schools file tutorials so we are on the same level (will provide a link).

In a sense what you will need to do is have a page with a drop down list with all of the different pages they can edit then have it post an ID to the next document. From there you will need to use the ID to open the file consistant with the ID and echo out the contents of the file to the textarea.

Then when you submit this it should take you to the preview page where it will also save the new contents to the document so you may need to post the ID of the page once more in a hidden field so as this document knows the file to reference also.

So from then on whoever goes to the page they have just edited it will be as they eddited it. And when they return they will have what they last changed in the textarea as you are reading the file before they edit it again.
